BOX-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 582,947', dated May 1S, 1897.

Application tiled July 9, 1896. Serial No. 598,554. (No model.)

To all whom t may concern:

Be it known that I, PAPHRO D. PIKE, of Stowe, in the county of Lamoille and State of Vermont, have invented a new and Improved Box-Nailing Machine, of which the following is a full, clear, and exact description.

This invention relates particularly to machines for forming and nailing circular boxes, such, for instance, as are used for packing butter or similar material, also covers for same, and the object is to provide a machine by means of which the rim of a box may be quickly and readily turned around the bottom port-ion andy nailed thereto, and in which the overlapped ends ofthe box may be quickly tacked together.

I willdescribe a box-nailing machine embodying my invention, and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of a machine embodying my invention. Fig. 2 is a top plan view thereof. Fig. is an end elevation. Fig. tis a plan View of a nail-carrier and form- Fig. 5 is a side elevation of said parts. Fig. 6 is a rear elevation of the nailcarrier, showing the devices for supporting the tacks employed in securing the lapped edges of the box together. Fig. 7 is a plan view of a completed box, and Fig. 8 is a side view thereof.

The machine comprises a frame l, on the top of which is journaled the drive-shaft 2 and a former-carrying shaft 3. On the driveshaft 2 is mounted a gear-wheel 4c, meshing with `a gear-wheel 5 on the shaft 3, the said gear-wheel 5 being smaller than the gearwheel 4t, whereby it may be rotated twice to one rotary movement of the gear 4.

On the outer projected end of the shaft 2 is mounted a nail-carrier 6, having a width substantially that of the box side designed to be nailed to abottom portion. This nail-carrier is here shown in the form of a half-circle, and arranged around the outer side at suitable distances apart are nail-holders 7. These nail-holders 7 are pivoted at one end to the outer surface of the carrier 6 and at their free ends have outwardly-projecting lingers 8,

which normally project beyond the periphery of the carrier, and they rare held yieldingly in this position by means of springs 9, secured to the carrier and engaging their free ends with pins extended outward in the holders. The finger portions S of the holders are extended at an angle relatively to the body portion of the holder, so that said fingers will project radially or substantially at right angles to the carrier. These finger portions may be suitably grooved on their inner surfaces to receive a nail, and these holders are'preferably magnetiied or made as permanent magnets, so as to hold the nail during the movement of the carrier.

At the inner side of each finger 8 a metal dri vin g-plate lO extends outward from the carrier. These driving-plates are designed to be engaged by the head of a nail and to force the nail through the box material, as will be hereinafter described.

Mounted on one end of the carrier (5 is a tack-holder ll. This tack-holder 11 extends across the end of the carrier and at its ends has upwardly-extended arms l2, having pivotal connection with links 13, adj ustably secured to the carrier. These links 13 have slotopenings through which a clamping-rod 14 passes, the said rod being provided with a head at one end and with a tightening-n ut at the other end, as indicated in Fig. 6. By adjusting these links 13 the projecting fingers 15 of the tack-holder may be made to extend more or less beyond the periphery of the carrier, and also by said adjustment the angle of said fingers may be changed with relation to the carrier.

rlhe holder 11 has any desired number of fingers 15, and the holder is pressed outward yieldingly by means of a spring 15a, secured this tack-holder will be magnetized similarly to the holders before mentioned.

On the outer end of the shaft 3 is rigidly mounted a holding and forming block 16,

IOO

around which the side piece of' the box material is designed to be wound. This former 1G is arranged forward of the carrier G, and the distance between the former and carrier is substantially that of the thickness of the box material. On this former 1G is mounted a clamping device for engaging the end of the box material, as indicated in dotted lines in Fig. 5. This clamp comprises a block 17, seated in a recess in the periphery of the former 1G and having a yielding connection therewith, so as to move slightly outward and inward with relation to the former. This block is shown as pressed normally outward by means of a spring 1S, seated in a socket in the former and engaging the inner side of the block 17. The block 17 at its free end has an outwardlyextended finger 19, which is very thin and is adapted to engage between the edge of the bottom of the box and the side wall thereof. As this finger is quite thin it is obvious that it will not change the circular formation of the box to any perceptible extent.

Coacting with the block 17 is a jaw portion 20, extending circumferentially of the former 16 and pivoted at one end thereto. This jaw 20 is seated in a recess formed in the outer surface of the block 17, and on its inner side it is provided with a lug through which a shaft 21 extends. This shaft 21 is provided with a cam-lug 22, adapted to engage against the wall of the recess formed in the former 1G, as shown in Fig. 5. The inner end of the shaft 21 is provided with a portion 23, turned at right angles tothe shaft and forming a handle or lever by means of which said shaft may be rotated.

In operation the thin or beveled end of a straight strip of box material .1f is placed between the free ends of the parts 17 and 20, and the jaw 2O is moved outward,to clamp the same by means of the cam 22. This jaw 20 extends entirely across the former 1o', an d it will be seen that as the parts are rotated the carrier 6 will force the block 17 inward tightly against the box material arranged between it and the jaw 20, the said jaw being held rigidly by means of the cam, as before described. Extended across the jaw portion is a metal plate 31, designed to be engaged by the ends of the fastening-tacks to elench the same.

Arranged forward of the former 1G and adapted to move toward and from t-he same is a clamp or holder 25, adapted to hold the bottom of the box in contact with the outer surface of the former 15. This clamp or holder consists of a metal disk mounted on an arm 2G, extended upward from a shaft 27, having longitudinal movement in bearings supported on the machine-frame. This shaft or rod 27 is preferably round, so that the clamp or holder 25 may be adjusted radially, if necessary, but to prevent its rotary movement while in operation l attach to it, by means of a set-screw, an arm 2S,which extends outward and has at its upper end a yoke engaging around and adapted to slide on the shaft Longitudinal movement is imparted to the rod or shaft 27 by means of a treadle 2E), fulcrumed to the machine-frame and having a link connection 30 with toggle-links 31 and 32, the link 31 being pivotally connected tothe machine-frame, andthe end of the link 32 opposite its connection with the part 30 has pivotal connection with the rod or shaft 27.

Obviously by pressing downward on the treadle 2f) the links 31 and 32 will be moved upward in parallel lines, and this movement of the links will move said shaft or rot 2" and cause the part 25 to engage closely against the bottom of the box previously placed against the former 16. If desired, the front face of the former 1G may be provided with pointed projections 33 to engage in the box material forming the bottom.

After the completion of a box it is desirable that the parts be brought to a stop, so that a knife may be operated to cut off the surplus material forming the side portion of the box. As here shown, this stop consists of a pin 34, extended outward from the gear-wheel 1- and adapted to engage with a projection 35 ou a lever 30, fulcrumed to the frame of the ma chine and having a weight .37.at its lower end which serves to hold the said lever in a substantially vertical position.

Mounted to slide on the upper side of the frame 1 is a bar 3S, having a cutter 30 at one end movable across the former 1G. This bar 3S has a slot-opening 40 at one end, through which a bolt tl extends to a connection with the machine-frame, and at its end near the cutter 3f) the said bar 3S is provided with a handle l2, After nailing the box material the cutter 3f) may be moved across the same to cut the under or surplus material below the line of transverse tacks t3, as indicated in Fig. 8.

In forming a box a straight strip of material is employed for the side. As before stated, the end of this stripfr: of material will be placed in the clamping device carried by the former, and as the said former rotates the strip will be curved or turned around the same. The strip is guided during this feeding operation by means of guide-arms -t-t, adjustably supported on an arm 45, extended upward from the machine frame. Each guide-arm 1lhas a fixed guide-finger etti and an adjustable guide-finger 47. The adjustable guide-finger 17has inits body portion a slot-opening through which a bolt passes to an engagement with the arm 4:5.

In the operation of the machine a nailwill be placed by an attendant upon each one of the nail-supports 7, and also the tacks will be placed upon the tack-holder 11. After the bottom portion of the box shall have been clamped against the former 1G the side strip a: may be placed in position, and then, upon a rotary motion imparted to the shaft i by means of the crank-handle thereon, the parts will be rotated to turn the side portion :e

around the bottom portion of the box, and the nail-holders 7 will successively present the nails, and they will begradually forced inward by means of the plate 10. Of course the nail holders 7 will be moved inward against the resistance of their holdin g-spri ngs by the contact of the iingers 8 with the material of the carrier 6. The tack-holder l will be brought into position and the several tacks i3 will be forced through the overlapped ends of the box material, and then after cutting off the surplus material the finished box may be removed from the former.

Having thus vdescribed my invention, I claim as new and desire to secure by Letters Patentl. A box-nailing machine, comprising a rotary former, means for holding the bottom of a box against the same, a rotary nail-carrier, and a series of nail-holders on said carrier, substantially as specified.
